a heavy lateral pressure is exerted between the outside faces of the outside driving boxes and the faces of the hubs of the drivers. This lateral pressure causes a great dealof wear at the contact po nts which causes an excess clearance between these parts known as lateral. This lateral inicommon practice is usually taken up by a removable hnermte'rposed between the drivers and the journal boxes, which liner may-be renewed as it is worn thin;

It istherefore an object posed between parts in the underframe'ot the locomotive to prevent too great a-playjbetween the hubs otthedriversand the faces of the driving boxes.

' Another object is to provide a novel, simple and'inexpensive means to be disposed between parts of the locomotiveunderframeto' I I I II liner, which'cohtact thesides'of the-filler take up axle lateral. I

A further object is to provide an effective means which may take the form of a tapered wedge provided with actuating means to eliminate play'between the locomotive axle I and the undert'rame.

A morespecific object is to provide a substantially U-shaped wedge adaptedto straddle the axle and to provide a simple and ac cessible actuating and locking means on said U-shaped member for the purpose of eliminating axle lateral and holding the bearings and wheels in correct and efficient:wOrln'ng position; i I i 1.] i

'With these and various "other objects in view, the invention may consists of certain no\ 'elteatures of construction and operation 1 as will be more fully described and particu larly pointed out in the specification, draw} ings and claims appended hereto.

In the drawings, wherein like reference characters are used to designate like parts Figure 1- is an elevation takentransverseof this invention to provide a novel means adapted to be inter- 5 I I I wedge-8, as shown in Figure 2, the tapered .face of which operatively cooperates with a correspondingly: taperedrace onflthe filler. block 5 1 This wedge is .-,provided with a substantially U-sh aped slot 9 which is a adapted to be fitted. around the, axle 2, and suitable of position.

Figure 3 is modification. of Figure 1, wherein the wedgesiare replaced by shims) The'jusual'locomotive drivers 1, which; are keyed'or otherwise'positioned on the @162, are

' carried by the engine undert'r'ame 3 through the mediumot suitable "bearings Bolted or otherwise secured; as at 16 ,Tto'the'bearings=1 i: 4 are suitable filler bl'oc k s5 which areadapted to be secured by suitablemeans 18*to the hi1 ers 7. F astened between these liners and located; substantially on the centerline of the engine is a suitable thrust bearing 6 having i suitablefadjusting meansi17 provided thereon; Between the filler block and the liner in the preferred form, is provided the" tapered lugs orvshoulders 10 on either 'side of-the.

block to prevent the wedge fromworking out In way "f" the taSten'ing'bolts'lS provided I between the tiller block and the liner, there are suitable slots 11 of anumber corresponding to the number of bolts, which allow the wedge tobe adjusted vertical-1y. At the top ing a suitableslot13 which is adapted to carry suitabledocking-and adjusting means 119 which areshown as' a nut and bolt arrangemerit, the bolt being'threadedin a suitable block; I As'alreadyl described, thewedge is of.

tapered form; having its widest part 14 disposedat the top and gradually tapering to a thin part 15Idisposed on either side of the axle slot 9. The shoulders 10 serve as stop members to prevent "rotative or sidewise "movement of the wedges by cooperating with the filler blocks 5 and also serve as positionv ing members or guides in conjunction with the guiding slots lL l, I

;a filler block, a liner, and means adaptedto lateral.

In the modification, illustrated inFig. 3, the wedge 8 is replaced by a shim 8 which may be substantially the same shape as the wedge, having the axle slot and holes in way of the fastening bolts 18, but it will be seen that this shim 8 is of constant width and the holes may be round to pei fectlyffit the fastening means 18. With the wedge, it will be seen that any predetermined "clearance between the faces of the hub of the driver; filler, bl k, a d a U- h d member intercan be provided and maintained, any looseness which may appear due to wear beingtaken up by means of the positioning bolts 19 provided for the top'ofthe wedge. This provides a very simple take-up and one which is eifective as well as positive. Innieappncation of the shims, it is of course understood that new shimshave to be provided or additional shims must be added for eachamoiiiit of lateraldesired to be eliminated, I I
